speakers, if there is one?

P.s.- I saw Hendrix twice. Even as a teenager, I knew it was something
special.

As far as I know, the "F" indicated the speaker was OEM in a Fender
the "6" indicates it was 16 ohm impedance

I'll see your two and raise two.
I even talked with him once before he became too famous.

Thanks. Exactly what I needed to know. Is it true that JBL toughened up the
design of the D120 for use in guitar amps, then called it the D120F, for
their biggst customer, Fender?

I'm not sure if there was any toughening up changes.
Some were painted a bright orange and some had a copper
colored dust cover instead of aluminum.
BTW, even if a frame is marked "-6" it may have been
reconed with an 8 ohm kit...

I'm pretty sure the baskets were gray in the 60's, then changed to orange in
the 70's. Same speakers, though.

Orange for Fender, regular ones were always gray, I'm pretty sure.

@bellsouth.net says...
treated edge and they loosened up the tolerance in the voice coil gap
slightly. Orange frames were OEM Fender, but grey frame D120F's were
also sold as part of the Signature series. The K120 was the 70s version,
some say designed to get around the Nixon wage/price freeze, but they
did increase the power rating. Note that most older JBL's are reverse
polarity and the power ratings are supposed to be cut in half when used
in open back cabinets. See the tech notes at the http://www.jblpro.com
site.

I was once told the coil form was made a little stronger.

Fender also had Gauss make some speakers for them painted orange.

GREAT speakers. Very early versions (I think before Fender) had
the older 3" voice coil. Should JBL ever get the smarts to re-enter
the Guitar amp world, THAT is the speaker they should produce.
What is left of the Standel amp company came *THIS* close to re-pro'ing
JBL speakers, even had one reviewed in a Mag (GP I think) which was the
3" VC version, and got RAVE reviewed. Plans ended for some reason.

Yes, what a rich history they have. WHY they don't do something
with it is beyond me. Hammond Ind. (not the organ or t/former companies)
owns them, and I think they also have ties in the MI field too. Why
don't they see what a statement they could make with a reissue MI speaker?

That would have ruled.
I'd *love* to be able to get new D140s.

There definitely were --
guitar players were putting the
original 15" JBL theater/hi-fi
woofer, the D-130, in guitar
amps, and getting magnificent
results until the voice coils
bottomed out and the speaker
failed. The "F" changes
included stiffening the
suspension (not sure if that
was done via the surround alone
or if the spider was also
redesigned) to prevent that
problem, making the resulting
D-130F (and the 12" follow-on
D-120F) reliable in high-volume
guitar applications.

My bad, you are right..

Great post, HG knows his shit. A true icon in this world, and the next..
BTW..he was a big wig at Acoustic, and involved with
the dreaded 'Delta Concept One' amp that was designed to
put PV out of biz. It didn't, but HP said it DID scare
him a little. My schematic for it is a hoot:

> Not sure where this info came from? All 12" and 15" Gray Frame JBL's made for musical instrument use where manufactured with a continuous paper cone (No Textile Edge) with the exception of the D-140 (15" Bass Speaker) They started using textile edge cones with the introduction of the Black Frame K-Series. These where the same speakers the orange and black units where based on. If you have or have seen a grey frame 12" with a textile edge (it has been re-coned) The -6 is indeed a designation for 16 ohm. The only change to the tolerance in the voice coil gap was done in products after the original D-130. All 120 series speakers D,K,E voice coil gaps are exactly the same.
